I use this BB on my steel retro-spec beater, it works perfectly fine and I also have one but a different spindle size on my Puegot road bike. This BB in general is a great one to buy if you need to replace an old one, quick, easy to install, and spin smooth. The spindle hasn't frayed on me either and I've switched crank arms multiple times as well. It's an all around great bottom bracket. Downside is ......well it is a bit heavy.
